At 690 V it still breaks 6.3 kA, which covers most motor circuits in a 690 V distribution. That matters when the breaker lives near a kiln or in a non-conditioned switchroom. At 55 °C it drops to 238 A, at 60 °C to 225 A, at 65 °C to 213 A, and at 70 °C to 200 A. If your panel ambient runs 60 °C, you need to size the breaker for 225 A or less. The ETU850 release provides communication function (likely via a communication module) and an undervoltage release is fitted as standard. Latching endurance is 20 000 operations — that is the mechanical life for the switching mechanism, not the electrical endurance under load. ## Panel integration and dimensions The 3-pole design fits standard busbar systems and panel cutouts for SENTRON 3VA frames. The basic switch (the switching mechanism) is order code 3VA2225-7KP32-0AA0, and the integrated auxiliary trip is 3VA9608-0BB25 — these are the internal sub-assemblies, not field-replaceable by the end user.","metaTitle":"3VA2225-7KP32-0DC0 SENTRON MCCB, 250 A, 3-pole, ETU850, 330","metaDescription":"SENTRON 3VA2225-7KP32-0DC0 molded case circuit breaker, 250 A rated continuous current, 3-pole, ETU850 release, 330 kA at 240 V.
